POLICE have executed a search warrant on a fifth property today near Emu Vale which is believed to be in relation to a drug network.
This follows police from State Crime Command searching a property near Yangan yesterday.
It is believed the searches are in relation to the 40-year-old investigation into the disappearance and presumed murder of Barbara McCulkin, 34, and her daughters Vicki and Leanne.
An alpaca farm and two homes were also raided in Warwick last week.
At this stage it is unknown if anyone from Emu Vale has been charged.
More to come.
